Case ReportsFailure of neuraxial anaesthesia in a patient with Velocardiofacial syndrome.
Velocardiofacial or 22q11 deletion syndrome is a genetic condition caused by deletion 22q11, the deletion of a small segment of the long arm of chromosome 22. To our knowledge this is the first case report of a woman with Velocardiofacial syndrome presenting in late pregnancy for caesarean delivery. ⋯ In addition examination revealed micrognathia and scoliosis. Neuraxial anaesthesia was unsuccessful and subsequent conversion to general anaesthesia was necessary despite concerns regarding her facial abnormalities, pulmonary regurgitation and mild intellectual impairment.

Case ReportsLower extremity radicular pain after prophylactic intrathecal saline injection through a subarachnoid catheter following accidental dural puncture.
We describe a case in which severe lower extremity radicular pain occurred after administration of 0.9% saline into the subarachnoid space through a catheter that had been left for 20 h following inadvertent dural puncture in an obstetric patient. A 42-year-old (G8P7) woman was admitted for repeat cesarean delivery. Accidental dural puncture occurred during epidural placement. ⋯ Subsequently, the patient developed a postdural puncture headache that persisted for three days. The patient's radiculitis and paresthesia likely resulted from an acute increase in intrathecal pressure after saline administration or from direct catheter irritation. Although both intrathecal saline administration and subarachnoid catheter placement have been previously proposed as ways to prevent postdural puncture headache, their efficacy remains controversial, and we advise caution with these techniques.
